Cancel subscription

Cancel subscription

For this service the following endpoint must be consumed: 

  1. https://sandbox-merchant.greenpay.me/subscriptions/cancel

Below is the step by step to successfully unsubscribe in our API:


1. Create JSON object to be sent 

The JSON must be structured as the following: 

JSON to send in the request example
  1. {
  2.    "subscriptionId": "id returned when subscription was created",
  3.    "merchantId": "your merchantid",
  4.    "secret": "your secret",
  5.    "user": "Some user name",
  6.    "reason": "Some reason to cancel subscription"
  7. }
Parameters description
  1. subscriptionId: Identifier received in the subscription creation response.
  2. merchantId: merchant provided by Greenpay.
  3. secret: secret provided by Greenpay.
  4. user: user who's cancelling the subscription.
  5. reason: cancelation reason.

Recommendations
  1. “User” and “reason” parameters are to follow up the user who canceled the service.

2. Send cancellation request.

An HTTP POST request must be sent to the endpoint. This request must include the JSON object that contains the subscription data.

Once the subscription has been sent and has been successfully completed, a JSON object is obtained in response.

Upon receiving this response, the parameter that must be obtained from the JSON object is the “body”, this one contains the cancellation result. The following code shows the response received after sending a subscription request.
